The Beatles were a British rock music group from Liverpool, England held in very high regard for both their artistic achievements and their huge commercial success, and have amassed an enormous worldwide fanbase that continues to exist to this day. Comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr, the group shattered many sales records and charted more than fifty top 40 hit singles. They were the first British pop act to achieve major ongoing success in the United States, scoring twenty #1 hits in the USA alone, becoming the biggest musical act of the twentieth century. EMI estimated in 1985 that the band had sold over a billion records worldwide . Their ballad " Yesterday" — written and sung by Paul McCartney (though officially credited as written by Lennon-McCartney) — is the most- covered song in the history of recorded music (about 2500 versions of it exist).
Their earliest compositions were mainly rock ‘n’ roll or R&B-rooted pop songs with the occasional ballad. But they grew increasingly eclectic as composers, arrangers and performers over the years. They composed songs and arranged them in a wide array of musical styles – occasionally fusing genres. The constant factor in the vast majority of their songs was their focus on melody. Despite the wide array of musical styles utilized, Beatles recordings were readily identifiable because of their distinctive vocals. In addition to their core pop and rock styles, The Beatles canon included songs flavored with folk, country, rockabilly, blues, soul, doo-wop, ska and many other musical genres. They were also pioneers of new musical directions such as psychedelia (with "Strawberry Fields Forever") and early heavy metal (with "Helter Skelter"). Their use of George Martin’s chamber and baroque orchestrations on songs such as "Yesterday", "Sgt. Pepper's Lonely Hearts Club Band" and "Eleanor Rigby" was another first in contemporary popular music.
